SAFETY ANTIJIMMY WINDOW LOCK Filed May 16 1950 INVENTOR. wag/4 amp/Jami? Patented Feb. 5, 1952 UNITED STATES P 5 Claims.

This invention relates to a safety jimmyproof window lock.

It is an object of the present invention to provide a window lock whereby access to the lock cannot be had from the exterior of the window and wherein the connection of the lock with the window is effected between the two'windows in such a manner that access cannot be had for the padlock and wherein there is a container for the padlock which is hinged to the inner window and which will contain the padlock in such a manner that access to the padlock can be had only from the inner side of the window.

Gther objects of the present invention are to provide a safety anti-jimmy windowlock which is of simple construction, inexpensive to manufacture, has a minimum number of parts, does not interfere with the operation of the window, and is compact, tamperproof and efficient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Fig. l is a perspective view of the assembled parts of the safety lock embodying the features of the present invention and of the window parts.

Fig. 2 is a vertical sectional view taken on line 2-2 of Fig. 1.

Referring now to the figures, i represents an upper window having a bottom frame rail l l To this frame rail there is attached a plate l2 from the inner edge thereof. This plate is attached by means of screws IS. The bottom end of the plate I2 is turned under the under face of the piece I l.

The upper end of the vertical plate 12 extends upwardly above the upper face of the piece I l and is provided with a hole I4 through which the hasp of a padlock l5 can be extended.

Before the padlock is put in place, a container 16 having sides and having a slot i1 is dropped over the upper end of the vertical plate II and is hinged to upper frame'rail l 8 of a lower window sash IS. The hinging of the container I6 is effected through a hinge part 2| connected to the inner face of the frame rail I8 by screws 22 and also by hinge parts 23 and 24 disposed respectively at the opposite sides of the hinge part 2| and by screws 25 and 26 respectively. The hinged end of the container I6 is open, as indicated at 21, so that the hasp of the padlock can be inserted into the opening 14 of the vertically extending plate 12. Access cannot be had to the padlock except through this opening 27. Accordingly the padlock is covered so that it cannot be tampered with from the outside of the windows and so that tools working between the slit between the win dows cannot contact the padlock.

' When it is desired to open the window, the padlock I5 is removed from the container [5 through the open end 2? thereof after first lifting the hasp from the opening it in the vertically extending plate 52. The container it is hinged over to the position shown in dot and dash lines in Fig. 2. The windows can be moved up and down as freely as with windows without the locking arrangement. In order to insert and lock the hasp of the padlock it is necessary to put the padlock in an inclined position within the container in order to have sufiicient support on the upper end of the plate 42 for pushing the hasp into the padlock.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

Having thus set forth and disclosed the nature of my invention, what is claimed is:

1. In a safety anti-jimmy window lock having a vertical plate adapted for connection to the lower rail of an upper window sash and adapted to project above the same, said vertical plate having a hole in its upper end and adapted to receive a hasp of a padlock, a container having sides and an opening in the bottom thereof adapt-- ed to receive the upper end of the vertical plate and the said padlock disposed within the container.

2. In a safety anti-jimmy window lock having a vertical plate adapted for connection to the lower rail of an upper window sash and adapted to project above the same, said vertical plate having a hole in its upper end and adapted to receive a hasp of a padlock, a container having sides and an opening in the bottom thereof adapted to receive the upper end of the vertical plate and the said padlock disposed within the container, said container being open at its inner end for access to the padlock lying within from the inside of the window.

3. In a safety anti-jimmy window lock having a vertical plate adapted for connection to the lower rail of an upper window sash and adapted to project above the same, said vertical plate having a hole in its upper end and adapted to receive a hasp of a padlock, a container having sides and an opening in the bottom thereof adapted to receive the upper end of the vertical plate and the said padlock disposed within the con tainensaid container being open at its inner end and. means for hingedly connecting the inner end of the container to the upper edge of a lower window sash.

4. The safety anti-jimmy window look as defined in claim 3, and said hinge means comprising hinge plates adapted for connection to the front edge of the upper rail of the lower window sash and for connection to the top face of the upper rail of the lower window sash.

5. In a safety anti-jimmy window lock having a vertical plate adapted for connection to the lower rail of an upper window sash and adapted to project above the same, said vertical plate having a hole in its upper end and adapted to receive a hasp of a padlock, a container having sides and an opening in the bottom thereof adapted to receive the upper end of the vertical plate and the said padlock disposed within the contamer, said vertical plate having an outwardly turned flange adapted to engage with the under face of the lower rail of an upper window sash.
